Burning Storm (バーニングストーム) is a one-handed rapid-fired version of the Buster Cannon used by Future Trunks. First, Future Trunks places his hands forward at 90 degree angle and charges a blue energy sphere. Then he fires a barrage of energy spheres from the energy sphere at the opponent, inflicting a great deal of damage.
Future Trunks used this attack when he and Krillin traveled down into Dr. Gero's laboratory to find and destroy Imperfect Cell's larval form. While looking around the lab, Future Trunks discovered the blueprint plans for Android 17 and took them in order to discover his weak spot. Satisfied with what he had obtained, Future Trunks, along with Krillin, destroyed Dr. Gero's lab and his super computer containing the Cell embryo with the Burning Storm, blowing the entire lab to bits.
Burning Storm was named in the Budokai Tenkaichi series and is one of Future Trunks' (Sword) Blast 2 attacks in his base and Super Saiyan forms. It also appeared in Dragon Ball: Raging Blast as one of Trunks' (Sword) Super Attacks.
